RY2KS Series Latch Relays Self-maintained Latch Relays DPDT — 3A contact capacity The RY2KS series latch relays have a self-holding function using permanent magnets in the magnetic circuit. Applying a voltage on the set (or reset) coil operates the armature and retains the contacts in that position until the opposite coil is energized, hence the latch relays are ideal for memory and flip-flop circuit applications. • Mountable in the same space as other miniature relays using the same sockets. • Recognized by UL and certified by CSA.

Notes: 1. For the relays with check button, use the parenthesized holddown springs shown in the above table. When the spring is used, sockets cannot be mounted closely side by side. 2. Leaf springs come in pairs. 3. Use the hold-down springs in environments where the relays are subject to vibrations or shocks. For details about sockets and hold-down springs, see page 386.
